Nick_shoots_fast Posted February 26, 2020 Share Posted February 26, 2020 (edited) I go thru these springs once every couple months! The last one it literally broke in half and not sure why! The guy at Dillon gave me some advice on what to do but it doesn’t seem like it will work. He said to change out the metal locator tab that rotates the primer assembly. I did just that on this time around but wondering if anyone else has experienced this. Edited February 27, 2020 by Atlasguy321 Link to comment Share on other sites More sharing options...
m700 Posted February 27, 2020 Share Posted February 27, 2020 I'm 10000 rounds in and haven't broken one. It's not automated is it?Sent from my Pixel 2 XL using Tapatalk Link to comment Share on other sites More sharing options...

Sent from my Pixel 2 XL using Tapatalk No it’s not. They said the metal piece that rotates the circle primer disc may be worn. I switched it out along with the new spring but I dunno. Thought it was strange. Link to comment Share on other sites More sharing options...
Furrly Posted February 27, 2020 Share Posted February 27, 2020 If the primary arm that advances the disk is bent it will wear out the springs, change it if haven't already Link to comment Share on other sites More sharing options...
Balakay Posted February 27, 2020 Share Posted February 27, 2020 They break. I go thru them every 15k rounds or so. When the primer disc starts to intermittently not index, change the spring. Link to comment Share on other sites More sharing options...
Brooke Posted February 27, 2020 Share Posted February 27, 2020 (edited) One of the answers above I agree with. Look at the arm on the primer index pawl. If it's bent upwards it tends to kink the spring and break it. I have usually just removed it and hammered it back to flat. Worked fine. There are 3 places on the 650 where springs are used in a curved service rather than tension or compression they are designed for. All three are weak points in the design of the press but they allow some flex of parts that might otherwise set off primer or crush a casing. Personally I ditched 650's and went to 1050's. This was a major reason for that. The 650 also has a lot of stamped parts that lead to failures in heavy use. The 1050's don't have such parts. The primer pawl is a good example.

conditionone Posted February 27, 2020 Share Posted February 27, 2020 I disassemble my 650 once a year for cleaning and lubing. That's about 20k rounds. I have not found a broken primer spring in six years but that spring is always deformed so I replace it. Link to comment Share on other sites More sharing options...
conditionone Posted March 1, 2020 Share Posted March 1, 2020 Just did my yearly maintenance on my 650. Yup, broken spring. Link to comment Share on other sites More sharing options...
clw42 Posted March 2, 2020 Share Posted March 2, 2020 (edited) I've broken a few of those myself, and my primer indexer looks fine. I've also broken a few of the shell plate indexer return springs. They just wear out. I can't tell you round counts at each breakage but I've probably got about 50K on the press.
